Kate Fransen and Claire Phyn will provide an update on two projects that are specifically targeting reductions in dairy farm nitrogen losses for improved freshwater quality.

The Sustainable Food and Fibre Futures Plantain Potency and Practice Programme, led by DairyNZ, is a seven-year Aotearoa-wide collaborative research and development initiative (2021-2028). It aims to assess the effectiveness of Ecotain plantain for reducing nitrate leaching. Farmlet trials at Lincoln and Massey universities are measuring leaching and production in farm systems with different levels of plantain. Partner farmers nationwide are collaborating with scientists to develop region-specific management practices. Kate Fransen will present an update of results and implementation.

The Low N Systems research program, also led by DairyNZ, explores stacking mitigation options to achieve on-farm nitrogen loss reductions of over 40-60%. A farmlet trial is demonstrating a profitable and practical stacked Low N system by combining tactical management practices, lower nitrogen fertilizer use, diverse pasture species (plantain and Italian ryegrass), and wintering on pasture and baleage instead of crops. Research is also underway to create a real-time bulk milk-based indicator tool for farmers to manage their herd's dietary nitrogen surplus and minimize the risk of higher urinary nitrogen losses.


Kate Fransen, Senior Project Manager, DairyNZ

Kate comes from a farming background and is passionate about working with scientists and farmers to develop systems that meet environmental and profit outcomes. Kate has led several large farm systems research, development and extension initiatives in New Zealand and Australia. She currently leads the Plantain Potency and Practice Programme and the wider Solutions at Scale for Water Quality programme at DairyNZ.

Dr Claire Phyn, Principal Scientist, DairyNZ

Dr Claire Phyn has over 20 years’ experience in dairy science. Her work has ranged from farm systems research into once-a-day milking to investigating the biology underpinning cow health and productivity during the transition period.

Claire previously led the multi-organisation “Pillars of a New Dairy System” research programme that developed novel genetics and management solutions to improve dairy cow fertility, health and longevity.
